Solidity method hash mismatch

[kumavis]

im having an issue calling a solidity function
following the trace in the stack and comparing to byte code I can see that it is trying to match the target function signature and the available function signatures
but there is no match and it falls past all of them and hits the STOP

web3 is 0.4.2, solc is 0.9.21

methods

• 0c9d7d48
• 141961bc
• 19ac74bd
• 278ecde1
• 2c0f7b6f
• a87430ba
• c1cbbca7
• e1152343

target

• bfe04e52

hard to tell but it seems like this is where cpp is generating the hashes of the methods
u256(FixedHash<4>::Arith(it.first))

whereas web3 does this
web3.sha3(web3.fromAscii(this._name)).slice(2, 10);
https://github.com/ethereum/web3.js/blob/25d9f5121735b76481b2518fe49ae285b75bac4d/lib/web3/function.js#L71-L73

The ways to generate the hashes are the same: web3.sha3 returns a string of the form "0xabcde...", so slicing it at (2, 10) is correct. Can you tell us the signatures of the functions?

This turned out to be my fault, my web3.sha3 was not ignoring the 0x at the beginning
